Allright, on another message board I keep up with, someone decided to take the info already released about 4e (y'know, all the little previews) and playtest it. I won't repeat them here, but I thought the people here might like to see the results.
For what it's worth, I trust this guy's judgement about game balance. After buying Monte Cook's World of Darkness, he managed to demonstrate that it had serious issues with the mechanics, in an easy-to-understand manner with some direct examples from the material in question. And managed to be entertaining, too.

Oh, and I suppose I should give fair warning. The Gaming Den is very tolerant of language that other message boards discourage.
